A school of colorful tropical fish swim across a deep blue background, rendered in a cheerful illustrative style with bold outlines and flat color blocking. Yellow, orange, red, black, and white fish of varying sizes and patterns fill the composition in a repeating, rhythmic arrangement that evokes the dense activity of a coral reef. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
